IMPROVEMENT IN ANTI-FRICTION DEVICES FOR THE AXLES 0F MACHINERY.

Specification forming part of Letters Patent No. 58,739, dated October 9, 1866.

To all whom it may concern.'

Be it known that we, NICOLAS BAILLY, of the town of Vesoul, in the Empire of France, agent of Eastern Railway of France, CHARLES DURAND, of the town of Jussey, now atEpinal, in the said Empire of France, chief draftsman of the said railway, GEORGE HOWARD MESNARD, of No. Al Viiniera, Vandsworth Road, in the county of Surrey, England, engineer, and ZAOHARIE POIRIER, of No. 2 The Grove, South Lambeth, in the said county of Surrey, England, merchant, have invented improvements in the application of rolling friction to the axle-boxes and journals of runnin g shafts and axle-trees of machines and vehicles of all descriptions for lessening the resistance to the motion; and we hereby declare that the following is a full and exact description thereof, reference being had to the annexed sheet of drawings.

It relates to improvements in the applica-- tion of rolling friction, as hereinafter described, and shown in the drawings, of a cyl! inder running freely upon the axle or shaft, or on a lining fixed thereto, supported on spheres, which spheres, or other equivalent supports, enter or work upon a throat or shoulder formed on the lining shaft or axle. The ends of the cylinders are cut away in a (lished and coned form to receive the spheres in suitable openings or embrasures.

The annexed sheet of drawings shows the application of our invention to the axles of horizontal and vertical shafts or bearings in machines, road and railway, and other carriages, Src.

Figure 1 is a longitudinal sectional view of the axle-box of a road-carriage where the wheel rotates and the axle is xed.

Upon the axle A of the carriage is immovably fixed a cylindrical piece, B, on the exterior of which, at the end, is turned the throats a a a a and two grooves, b b, in which roll spheres G, which support a cylindrical envelope, D, made in one, two, or more pieces, in the .ends of which cylinder are cut coned and curved embrasures or openings to receive the working spheres E, which rotate in or upon the throats or shoulders tra a. a, before described, and in or upon the throats or shoulders e c e e turned in the end plates F, which are fixed to the wheel by bolts or other suitable-means, and which will be so arranged as to exclude dust and dirt from entering the box.

It will be easily seen from this arrangement there can be no movement in the direction of the length of the axle, and only a rolling movement upon the spheres E, which spheres, being embraced and kept equidistant by the cylindrical piece D, (which piece is carried round by the rolling action,) turn horizontally in their onward progress, thereby ever 1changing the surfaces in contact. The effect of the cylindrical piece D, with its einbrasures, is such as tov cause the working spheres E to turn about inv every sense, and the effect of the action of the parts is such that the sphere has always a tendency to wear itself true.\ This cylindrical piece D bears only its own weight on the spheres, and, its duty being simply to keep the working spheres E equidistant from eachv other, it has little or no work to do, and can never, therefore, develop frictional heat suficientvto render the bearings, shaft, or axle heated to any injurious extent.

Fig. 2 is a sectional end View, showing the working spheres E. Fig.3 is a section through the cylindrical envelope D, showing the supportingspheres C. Fig. 4 is a plan of the cylindrical envelope D. Fig. 5 is an elevation of the end plates F. Fig. G is an arrangement similarv to that described, Fig. l, for a long bearing in carriages or machinery where the axle or shaft rotates and the wheel is fixed thereto, the same letters of reference as before applying to the same respective several pieces or parts thereof. This drawing shows the throats a a. a a turned upon the axle or shaft A, dispensing with the cylinder B, which is not required in all cases. Figs. 7, 8, 9 show the arrangement when applied to large shafts or axles, where the bearings are short, the saine letters of reference as before applying to the same respective several pieces or parts thereof. The supporting-spheres C in this case are dispensed with.

For upright or vertical bearings for shaft1 FFT.

ing, mill-gear, dock-gates, and all other like purposes, We referto Figs. l() and 11 on the sheet ot' drawings.

Fig. l0 is a section through one of such bearings.

The figure A represents the foot ot the shaft or other superineunibent pressure, `which is to be formed with apivot on the under side. B is the cover or turn-table of the apparatus, with a recess to receive the pivot on the piece A, and a throat on the under side to receive the Workin g spheres'G; C, the Working spheres, which may be of any required number and size; D, the dished piece, with embrasures on the edge to receive and keep the spheres C equidistant, which dished piece D runs freely round with the spheres 5 E, the pivot and maintaining-screw for the above; F, the ease or dished basin in which the spheres rotate.

Fig. l1 is a plan of the apparatus with the cover B removed..

The metal which We prefer to use for the sumiorting-spheres and other parts of the apparatus is cast-iron; but other hard metals may be used.

Our invention and the manner of carrying it into effect being now described, We Wish it to be understood that We do not eonne ourselves to the precise arrangement as shown in the accompanying sheet of drawings so long as the peculiar featureswof our invention be retained.

What We ela-im as new, and desire to secure by Letters Patent, is-

The combination and arrangement of the several parts for the production of an anti- 'rietion bearing` for rotating shafts, substantially as hereiuset forth.

In witness whereof We, the said GEORGE Hownnn MnsNAnn, ZAGHARIE PoIR1nn,NIooLAs BAILLY, and CHARLES, DURAND, have hereunto set our hands and seals.
